pickle.load/loads on non-constant data executes arbitrary code on deserialize. Use JSON or a signed/whitelisted format for untrusted input. (Apache-2.0.)

### Impact Pillow did not limit the amount of GZIP-compressed data read when decoding a FITS image, making it vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe perfor…

This is the same issue as CVE-2024-3651, however the original remediation in 2024 was not a complete fix. Payloads such as `"\u0660" * N` or `"\u30fb" * N + "\u6f22"` utilize the `valid_contexto` function prior to length rejection, and for high values of `N` will take a long time…

### Summary `PIL/BdfFontFile.py` `bdf_char()` (lines 84–88) reads the `BBX width height` field from a BDF font file and passes the dimensions directly to `Image.new()` without calling `Image._decompression_bomb_check()`. This completely bypasses Pillow's documented decompression …

## Description `PIL/GdImageFile.py` `GdImageFile._open()` reads image dimensions from the GD 2.x header and stores them in `self._size` without calling `Image._decompression_bomb_check()`. Because `GdImageFile` is **not registered with `Image.register_open()`**, it never passes …

## Description `PIL/PcfFontFile.py` `_load_bitmaps()` (line 227) reads glyph dimensions from the PCF `METRICS` section and passes them directly to `Image.frombytes()` without calling `Image._decompression_bomb_check()`. Dimensions originate from unsigned 16-bit values: ``` xsize…

### Summary Pillow's EPS parser (PIL/EpsImagePlugin.py) accepts a negative byte count in the %%BeginBinary directive. A crafted EPS file can cause Image.open() to seek backwards to the same directive and parse it repeatedly, resulting in an infinite loop and CPU denial of servic…

Passing nested lists as coordinates to APIs that accept coordinates such as `ImagePath.Path`, `ImageDraw.ImageDraw.polygon` and `ImageDraw.ImageDraw.line` could cause a heap buffer overflow, as nested lists were recursively unpacked beyond the allocated buffer. Coordinate lists a…

### Impact An attacker can supply a malicious PDF that causes the process to hang indefinitely, consuming 100% CPU and making the application unresponsive. ### Patches Patched version: 12.2.0. PdfParser (introduced in Pillow 4.2.0) follows Prev pointers in PDF trailers to read …

If a font advances for each glyph by an exceeding large amount, when Pillow keeps track of the current position, it may lead to an integer overflow. This has been fixed.

### Impact Processing a malicious PSD file could lead to memory corruption, potentially resulting in a crash or arbitrary code execution. ### Patches Patched version: 12.2.0 Pillow 12.1.1 addressed CVE-2026-25990 by adding checks for tile extents in PSD image decoding/encoding …

### Summary `src/libImaging/Jpeg2KDecode.c:853` accumulates `total_component_width` across every tile in a JPEG2000 image instead of recomputing it per tile. That accumulated value is then used in the `tile_bytes` calculation at `src/libImaging/Jpeg2KDecode.c:868`, which can make…

## Description `PIL/FontFile.py` `FontFile.compile()` assembles per-glyph images into a single combined bitmap using `Image.new("1", (xsize, ysize))` without calling `Image._decompression_bomb_check()`. This is the base-class method shared by both `BdfFontFile` and `PcfFontFile`…

### Summary Pillow's public `ImageCms.ImageCmsTransform.apply(im, imOut)` API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. For example, a transform built as `RGBA -> RGBA` …

### Summary `PdfParser.PdfStream.decode()` in Pillow's `PdfParser.py` calls `zlib.decompress()` with the `bufsize` parameter set to the value of the PDF stream's `Length` field, without any upper bound on the actual decompressed output size. Python's `zlib.decompress()` `bufsize`…

### Summary Pillow's public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits. In 4-byte pixel modes such as `RGBA`, this becomes a controlled backward heap underwrite: for a source image of width `W`…

### Summary Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size. Minimal public API trigger: ```python from PIL import Image, ImageFilter im = Image.new("L", (3, 3), 128) im.filter(ImageFilter.MedianFilter(4294…

## Summary When Pillow loads an uncompressed image whose tile uses the `raw` codec and a mode in `Image._MAPMODES`, and the image was opened **from a filename**, it memory-maps the file and builds the image's row pointers directly into the mapping via `PyImaging_MapBuffer` (`src…
